WOODHEELATTACHING JACK.

Application led June .6, v1917'. Serial No. 173,134.

To all 'whom t may concern:

Be it known that I, FRED A. REARDON, a

citizen of the United States, land a residents` of Haverhill, county ,of Essex, andfState ofv Massachusettafhave invented an Improvement in Wood-Heel-Attaching Jacks, of which the following is a specification. y

ln attaching wood heels to shoes by the usual hand-nailing process, which,.fso far as l am aware, is the only process, at present, in practical use it is customary to apply glue to the heel orheel seat and then to clamp the heel onto the` seatin position 'and y hold it `thus clamped until `the glue sets,

after which the clamp is removed andthe.

attachingv nails are driven by. hand from inside the shoe, the glue being relied on to` hold the heel in place while is performed.

This method is objectionable for several reasons some of the more `important off which are, as follows :A considerable numher of clamps must; be provided, so that the workman may be continuously employed, this involving .the provision of space and apparatus; further,'the glue sometimes fails to hold the heel invposition until the heel is securely attached, and moreover it reauires considerableskill on the part of the 1 woodheel-nailer to perform the nail-drivingy Y the attaching nails may be drivenwhile the heel is thus held thereby,V and by providing, in connection therewith, nail-guiding means for causing the nails to be accurately d1- rected as they are driven;

In lthe accompanying drawing in which an embodiment of my invention is shown:-x`

Figure l is a side elevation of such a device. I y

Fig. 2 is a plan viewlthereof.

Fig. 3 is a .longitudinalsectional view, Q11 a this operation an enlarged scale, illustrating the manner of" driving the. nails.

Fig.` l is a detailplan view of the heel-y part last support and Figso and 6 are detail views of the opposite sides of the iion last.

According to my invention I provide a base l, whichs adapted to be rigidly secured to a bench, or other support, and a supporting bracket 2, comprising a pair of arms mounted on the end of'a shaft 3, and

. extending oppositely with relation thereto,

said shaft being rotatablyT mounted in a horizontal position in said base. Locking means are provided for holdingsaidl bracketV 2 with its arms disposed in a vertical plane, comprising a laolt 4t, mounted to slide in lugs 5, on the base and arranged to enter either` of diametrically opposite recesses 6 in the @hub 7 of the bracket 2. y A spring 8 is arranged on the bolt 4,' between oneofthe lugs and a collar 9 on the bolt, to press the bolt into either of said recesses and a linger 10 is provided on said bolt to alford a convenient means to withdraw the `bolt and unlock the bracket, so that it may be 1 rotated from one locked position tothe other.

A clamp frame, lil` of approximately ,'C-

form, is provided, from theback` of which two lugs 12 are arranged to pro]ect, the

faces, on the adjacent sides of the arms of bracket, 2, and said lugs being mounted on a pivot shaft 13, whidh is mounted at its ends in the arms of said bracket, so that said frame ll may swing back and forth through an are somewhat greater than a semi-circle,

The arms 11 and lll of said frame l1 en4 tend transversely of their pivotal support' and, at their end-portions, are extended toward each other, so that their ends lie in a 1 line which is approximately, though not necessarily, exactly, parallel to the pivot shaft 13. A heel-top engaging member, or block, 14 is connected by a pivot l5 to the end of the arm l1, said pivot being ar-` ranged at right angles to the plane of the frame 11, so that said block may swin `to a limited extent in said plane, the b och having a face formed thereon at the oppositeside thereof from its pivot, adapted'to shoe.

receive the top of an ordinary wood heel, a retaining lug 16 being formed at one side of said face.

A screw threaded post, or rod 17 is threaded in the other arm 11b in a position approximately perpendicular to the face of block 14, so that it may be adjusted to and from the same, said post having a ball 18 on that end adjacent the block 14 and a handle 19 at itsV opposite end. An inside mailing heel-part last is connected to the ball-carry ing end of said post 17 by a universal joint, as hereafter described, said last comprising la dieblock or nail plate 20, adapted to fit into the heel-portion' of the shoe and to eX- tend entirely over the heel seat thereof, the face thereof being formed to correspond to th usual formation of the interior of the A plurality of inwardly inclined bosses 21 are formed on the opposite side of the plate 20 from its face side, and about the side edges thereof, at the inclinations and in the positions in which the several heel-attaching nails are preferably driven, nail passages being formed through said bosses, which emerge in the face of the plate. A corresponding series of nail tubes 22 have screw threaded engagement with the ends of said bosses so that they extend in line therewith, and therefore divergently from the plate 20, and a series. of nail-guiding, spring fingers 23 are preferably clamped in position in said bosses by said tubes, see Fig. 3. The opposite ends of said tube 22 are extended through a supporting plate 24,4of similar shape to the nail plate 20, and are rigidly connected thereto by nuts 25 on said tubes, which clamp said plate against shoulders 26 on the tubes. In connecting the plates 20 and 24, it is convenient first to screw the tubes 22 into the bosses 21, and then pass the opposite ends thereof from the bosses through the apertures in the plate 24.` As the tubes extend divergently, it is necessary to provide apertures of somewhat greater diameter than that of the tubes, to permit such simultaneous insertion. To make the construction rigid, bushings 29 are placed on the tubes after the latter have been inserted and then are screwed into the apertures after which the nuts 25 are screwed onto the tubes. As shown in Fig. 4, the tube apertures in plate 24 are closely adjacent the side edge thereof, so that sufficient space is provided in the middle portion of the plate to permit the convenient attachment of the post 17 thereto. The particular means shown consist of a pair of clips 27 which are secured to the middle portion of the plate 24, about the ball 18, on the end of said post, recesses to receive which are formed in the adjacent sides thereof, so as to form a ball and socket joint connection between `said post and the die block, which permits universal tilting movement of said plate with relation to said post 17, as well as relative rotary movement of the latter.

In using the device, the bracket and frame are locked in the position of Fig. 1, so that plate 20 is face uppermost, and will tilt forward to permit the ready application of the shoe. Then the shoe is placed on the last and the heel, to the base of which a coating of glue has been applied is placed in position on the heel-seat of the shoe. The last is then forced upwardly by the screw post 17, until the top of the heel is forced against the topengaging block 14, both being tilted to the extent necessitated by the relative inclinations and positions of the top and base of the particular heel which is applied, as indicated by the dotted line position of Fig. l. The heel will thus be firmly clamped against the heel-seat of the shoe in the position in which it is to be attached, slight irregularity in the heel seat being compensated for by the universal joint connection with the post. The bracket is then unlocked and turned the opposite end up, so that the shoe is held bottom down, as shown in Fig. il. The usual attaching nails are then placed in the tubes, as also shown in Fig. 3, and are driven into the heel by the use of a hand drivel' 30, which is similar to, and used like an ordinary nail set, the driver being placed on the heads of the nails in the tubes and struck with a hammer, so that they are driven successively.

`On account of the inclined positions in which the nails are held, when first placed 1n the tubes, their points would tend to swing outward to such an extent that the nails would not be driven at the desired inward 'inclinations, 'unless roperly directed. This difficulty is obviated by the spring lingers 23, which hold the points of the nails in line with the center line of the tubes. The nails will thus be accurately guided, as they are driven, and will b driven in the position and at the inclina` tion which is most advantageous. Many ol the diiiiculties encountered in nailing by hand, in the ordinary way are thus avoided. Moreover, with the above described device. but little skill is required to enable the operator to drive the nails, while former methods re uire considerable skill and experience.

s soon as the nails have been driven, the shoe may be removed from the clamp, as the nails will hold the heel in position while the glue dries. The heel is thus attached by both glue and nails in practically the Same operation.

By having the whole clamp and support mounted to rotate about a horizontal axis, the heel may be positioned with the shoe bottom side up, which is the most advantageous position in which this may be done, and may then be turned over and nailed while held bottom down. By providing the lll pivotal connection between the clamp and Vits support, the clamp may be swung laterally, iirst to one side and then to the other, so thatthe workman may `drive the nails conveniently without changing his position in front of the jaclr. The whole operation may thus be performed much more rapidly than with previously employed hand methods, machines which drive the nails in a gang being, so far as I am aware, but little used in attaching wood heels, by reason of their tendency to cause splitting of the heels.
